Intel Core Ultra 9 275HX
Arrow Lake-HX brings the desktop Arrow Lake die to laptops: 24 cores, a 5.4GHz ceiling and a 3nm compute tile. It is Intel's fastest mobile processor, comfortably ahead of the i9-14900HX in multi-core while drawing less power to get there.
Pros
- 24 cores and Intel's highest mobile multi-core throughput
- 3nm compute tile improves efficiency over Raptor Lake-HX
- Supports up to 256GB of DDR5-6400
- Arc-based iGPU is a real upgrade over UHD Graphics
- 36MB of L3 cache for heavy workstation tasks
Cons
- No Hyper-Threading, so only 24 threads from 24 cores
- 160W turbo power needs a large cooling system
- 13 TOPS NPU misses Copilot+ certification
- Only found in expensive desktop-replacement laptops
Very good
